TECHNICAL FIELD

The present invention relates generally to appliances for orthodontichardware and/or teeth. More specifically, the present invention relatesto devices, systems and methods for shielding orthodontic hardwareand/or deficiencies in one's teeth.

BACKGROUND

Orthodontic braces are designed to align and straighten teeth andposition the teeth in regard to a person's bite as a result of force andpressure on the teeth. The primary components needed to help move theteeth, in the case of traditional metal or wire braces, are brackets,bonding material, an arch wire, and ligature elastic, otherwise known asan “O-ring.” Over a period of time, the teeth move when the arch wireexerts pressure on the brackets and teeth. At times, additional forcemay be applied in specific directions by using springs or rubber bands.Although braces are an effective tool for ultimately aligning andstraightening teeth, some patients are hesitant to employ braces due tofinancial constraints, the known discomfort and unfavorable appearanceof braces, and undergoing the braces process typically takingapproximately two and a half years before the braces are removed.

Efforts have been made to minimize the discomfort and unfavorableappearance. Outside the pressure that braces place on a patient's teeth,discomfort is primarily caused by the brackets and the end of the archwire, each typically causing irritation to the lips, cheeks, gums,and/or tongue and sometimes causing mucosal ulceration. However, theefforts proposed to overcome the discomfort of braces or unfavorableappearance require bracket appliances only employable over specializedbrackets, an orthodontist to properly position the appliance over thebracket or arch wire, and appliances that interfere with the arch wire.These issues result in inefficiencies to the patient and are costly.

In addition, due to various factors, such as poor teeth maintenance,limited dentistry and/or orthodontic work, many individuals face issuesof tooth loss or the like. Tooth loss is highly conspicuous andunsightly and, due to financial constraints, often times cannot be fixedor addressed appropriately. These individuals may want a temporaryresolve that will minimize the unsightly and conspicuous nature of toothloss.

Therefore, it would be advantageous to develop an orthodontic appliancethat can be positioned by oneself over a bracket or arch wire that alsominimizes patient discomfort and minimizes the unfavorable appearance ofbraces. It would also be advantageous for the orthodontic appliance tobe adaptable to most any sized bracket while not interfering with thearch wire. In addition, it would be advantageous to provide a device andmethod that will minimize issues of tooth loss or unsightly teeth.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a simplified view of a bracket system 10 or bracessystem is depicted over a single tooth 5 and a cap 20 in an unattachedposition. The bracket system 10 may include a bracket 12 coupled andaligned on the teeth with an arch wire 14 or main wire configured toextend through each of the brackets with a ligature wire 16 coupling thearch wire 14 to the bracket 12. The cap 20 may be sized and configuredto be captured by the bracket 12 so as to be positioned over the bracket12, as depicted in FIGS. 1A and 4. Such cap 20 provides a smooth androunded surface that is non-abrasive to a patient's mouth, such as theirlips, cheeks, gums, and tongue. The cap 20 may be formed with one ofvarious shades of white. In another embodiment, the cap 20 may besomewhat transparent.

With respect to FIGS. 1-3, the cap 20, according to one embodiment, mayinclude a rounded body 22 with a mound-like outer shape. The body 22 mayinclude a wall 24 with an outer surface 26 and an inner surface 28 and abottom edge 30 extending between the outer and inner surfaces 26, 28.The body 22 may include a first channel 32 and a second channel 34 eachextending from the bottom edge 30 and into the wall 24 a predetermineddistance. The first and second channels 32, 34 extend from the bottomedge 30 at opposite sides of the body 22 and are aligned with eachother. The first and second channels 32, 34 may be similarly sized andinclude a fairly consistently sized gap 36 along their respectivelength. The gap 36 of the first and second channels 32, 34 is sized andconfigured to receive the arch wire 14 upon the cap 20 being placed overthe bracket 12 such that the cap 20 makes minimal or no contact with thearch wire 14 in the process of positioning the cap 20 as well as in theattached position of the cap 20. As such, the gap 36 of the first andsecond channels 32, 34 may be larger than the diameter of the arch wire14. Further, the gap 36 may be much larger so as to expand a majority ofthe side portion or width of the cap 20 as depicted with broken lines 31in FIGS. 1, 1A, and 2. Such enlarged gap may be useful for purposes ofmaking the cap, employing molding techniques, such as injection molding,or any other suitable molding technique, as known to one of ordinaryskill in the art.

Referring back to FIGS. 1-3, the cap 20 also includes multiple tabs 40.The tabs 40 provide a retention mechanism for the cap 20 to bemaintained to the bracket 12. Each tab 40 may include a base 42 and afree end 44, the base 42 being coupled to the bottom edge 30 or to theinner surface 28 adjacent the bottom edge 30 of the body 22. Themultiple tabs 40 may extend from the bottom edge 30 of the body 22 in aninward manner such that the tabs 40 extend toward oppositely facing tabs40. Further, in a first, un-attached position, the tabs 40 generallyextend to provide a partial bottom surface of the body 22 and further,extend in a common plane or a substantially flat configuration. Further,the tabs 40 may extend from the bottom edge 30 at their base 42 towardtheir free end 44 to generally define an opening 46, the opening 46extending to a hollow space 48 defined by the inner surface 28 of thebody 22.

In one embodiment, the tabs 40 may each extend from the bottom edge 30so as to be separate and distinct from each other. The tabs 40 may bediscrete relative to each other in that they may include a slit or gapthat separates each tab from an adjacent tab. As such, each tab 40 mayindependently flex, move and/or bend relative to each other. Further,each tab 40 may independently bend and provide a bias toward the first,un-attached position such that each tab 40 is resiliently flexible. Itshould be noted that there are no tabs 40 between the first and secondchannels 32, 34 so that potential interference to the arch wire 14 ofthe bracket system 10 is limited.

In one embodiment, the tabs 40 may include a depth thickness 50 that maybe less than a thickness 52 of the wall 24 of the cap 20. The tabs 40may also include a similar depth thickness 50 than that of the thickness52 of the wall 24 of the cap 20. In another embodiment, the tabs mayextend a tab length 54 so as to minimize a size of the opening 46 suchthat one free end 44 of a tab 40 is directly adjacent to an oppositelyfacing free end 44 of a tab 40. In another embodiment, adjacent tabs 40may contact each other along the respective tab lengths 54 so as tominimize any slit or gap between adjacently extending tabs 40. In stillanother embodiment, one tab 40 may slightly over-lap an adjacentlyextending tab 40 along their respective tab lengths 54 such that thetabs 40 may at least partially flex or move dependent upon an adjacenttab 40 moving or flexing.

As depicted in FIGS. 1A and 4, the cap 20 may be captured over thebracket 12 such that the tabs 40 are placed in a second, attachedposition. In the second position, the resiliently flexible tabs 40 maybe of a length so that the free ends 44 of the tabs 40 may engage with abase of the bracket 12 such that the tabs 40 bias against the base ofthe bracket 12 in a bent or bunched-up manner, as depicted in FIG. 4. Inone embodiment, in the second position, the tabs may be biased towardthe first position. The independently bendable tabs 40 provide aretention mechanism that can readily adjust to the variation instructure of an individual bracket 12. Also, the tabs 40 provide for aneffective retention mechanism for various bracket configurations. Inthis manner, the tabs 40 may readily engage the base of the bracket 12and retain and capture the cap 20 to the bracket 12. Further, since thetabs 40 do not extend over the channels or the space aligned between thefirst and second channels 32, 34, such arrangement facilitates the body22 to fit over the bracket 12 so that the arch wire 14 extends throughthe channels without interference to the arch wire 14 by the tabs 40 orthe body in the process of positioning the cap 20 over the bracket 12.

The body 22 and tabs 40 may be formed of a polymeric material, such assilicone, polyethylene, polycarbonate, polypropylene, polyvinyl chloride(PVC), or any other suitable polymeric material or combination ofmaterials. Coatings may also be employed in the manufacture of the cap20 on various portions, such as the outer surface 26. As known in theart of polymeric materials, the cap 20 may be manufactured employingknown techniques, such as extrusion, injection molding, blow molding,thermo-flowing, casting, transfer molding, or any other knownmanufacturing methods of polymeric materials. The cap 20 may be formedas a seamless unitary structure. The cap 20 may also be formed inmultiple components and then attached with known methods.

Turning now to FIGS. 5 and 6, in another embodiment, a cap 60 may besized and configured to capture an end 15 of the arch wire 14. The cap60 in this embodiment may include a spherical or a mound shaped body 61with a wall 62 having an outer surface 64 and an inner surface 66, theinner surface 66 defining a hollow space 68 in the body 61. Similar tothe previous embodiment, the cap 60 may include multiple tabs 70extending from an edge 72, the edge 72 defined between the outer andinner surfaces 64, 66. Each tab 70 may include a base 74 and a free end76. The tabs 70 collectively may provide a spoke-like configuration withslits defined between each tab 70. In one embodiment, the free ends 76of the tabs each may extend toward an axis 78 of the body 61 such thatthe free ends 76 of the tabs 70 collectively define an opening 80 thatextends to the hollow space 68 of the body 61. The tabs 70 may give wayto enlarge the opening 80 upon manually pushing the cap 60 over the end15 of the arch wire 14. Upon the cap 60 being positioned over the wireend 15, the tabs 70 are configured to bias against an outer surface ofthe arch wire 14 so as to retain or maintain the cap 60 over the wireend 15. With this arrangement, due to the cap 60 having a rounded outersurface 64, the cap 60 minimizes potential irritation and discomfortthat would otherwise be caused by the arch wire 14. Such cap 60 may beformed of any suitable polymeric material, such as those described inthe previous embodiment, and be formed employing known manufacturingtechniques as previously described and known in the art.

With respect to FIG. 7, another embodiment of a cap 90 provided over abracket system 10 is described. This embodiment is similar to the firstembodiment describing the cap and bracket system 10 discussed herein(FIGS. 1-4), except this embodiment includes a shield portion 92. Theshield portion 92 may be integrally formed, attached, or adhered to afront side of the cap 90. The shield portion 92 may be sized andconfigured to be positioned over an entire face of a single tooth 5 tosubstantially and aesthetically shield the braces of a patient. Suchshield portion 92 includes a face surface 94 and a back surface 96. Theface surface 94 may be a large smooth surface to protect the gums,tongue, and mouth from irritation and discomfort. The back surface 96 issized and configured to abut at least a portion of the face of the tooth5.

The cap 90 and shield portion 92 may be formed of any suitable polymericmaterial as previously set forth herein and be formed employing knownmanufacturing techniques. In addition, the shield portion 90 may beformed of a more rigid polymeric material, such as polyvinyl, or anyother suitable material, such as a ceramic, composites, laminates orcombinations thereof. The shield portion 90 may be formed separatelyfrom the cap portion and then adhered together with an adhesive. Theshield portion and the cap may also be formed as a unitary and seamlessstructure.

With reference now to FIGS. 8 and 9, a shield system 100 foraesthetically altering the appearance of one's teeth is disclosed. Thisembodiment provides similar structural characteristics of previousembodiments, however, this embodiment does not include a mound shapedcap. Rather, this embodiment includes a shield member 102 sized andconfigured to fit over a bracket 104. The bracket 104 may have a lowerprofile than brackets employed for braces. The bracket 104 is astand-alone or wireless bracket for temporarily adhering to one's teeth.The bracket 104 of this embodiment may be an attachment mechanism forthe shield member 102. The bracket 104 may include a base portion 106and an extension 108. The base portion 106 may be adhesively adhered toa person's tooth 105. The extension 108 may be configured to correspondwith an attachment portion of the shield member 102. The extension 108may include a square or rectangular configuration or any other suitableconfiguration sized to correspond and attach to the shield member 102.The bracket 104 of this embodiment may be formed of a polymericmaterial, ceramic material, or a metallic material, or any combinationthereof.

The shield member 102 may include a face portion 110 and a rear portion112 with a pocket 114 or hollow space disposed and defined therebetween.The rear portion 112 may include an opening 116 defined therein in theform of a horizontal slit or the like. The rear portion 112 may alsoinclude vertical and/or transverse slits 118, transverse relative to theopening 116, that define tabs 120 extending toward the opening 116 inthe rear portion 112. Such tabs 120 may extend around the opening 116defined in the rear portion 112. The face portion 110 may include a morerigid material than the rear portion 112. In another embodiment, theface portion 110 and rear portion 112 may be made of a common material,but be formed of different thicknesses so that the face portion 110 isthicker than the rear portion 112 so that the face portion 110 is morerigid than the rear portion 112. The tabs 120 may include structuralcharacteristics to facilitate maintaining the shield member 102 to thebracket 104.

As in previous embodiments, the shield member 102 may be formed of avariety of polymeric materials, such as silicone, polyethylene,polycarbonate, polypropylene, polyvinyl chloride (PVC), polyvinyl, orany other suitable polymeric material or combination of materials, suchas polyvinyl for the face portion 110 and silicone for the rear portion112. As set forth, the face portion 110 of the shield member 102 may beformed of a more rigid material, which may include ceramics, such asporcelain, and various composites and laminates that may includepolymeric materials. The shield member 102 may be colored in variousshades of white so as to shield any undesired deficiencies in one'steeth.

In another embodiment, the bracket 104 and shield member 102 arrangementmay be employed for changing the aesthetic appearance of one's teethwith a shield member 102 that is not colored with various shades ofwhite. For example, the shield member 102 may be gold or black in color.Depending on the color of the shield member 102, such bracket and shieldmember arrangement may be employed for a myriad of other purposes, suchas costume, popular culture, etc.

In still another embodiment, the shield member 102 depicted in FIGS. 8and 9 may also be employed to shield brackets employed for braces. Suchshield member 102 may be employed with a bracket system 10 for braces(See FIG. 1). As such, the opening 116 and tab 120 arrangement definedin the rear portion 112 would be employed similar to the cap discussedherein to engage a bracket for braces and the face portion 110 wouldprovide the advantageous features of protecting one's mouth fromdiscomfort as well as aesthetically shielding the braces. The shieldmember of this embodiment may provide a lower profile than theembodiment depicted in FIG. 7, for example.

With respect to FIG. 10, in another embodiment, a shield system 130 isdisclosed for aesthetically shielding a gap 132 in ones teeth. In thisexample, the shield system 130 provides for aesthetically shieldingdeficiencies in one's teeth, such as tooth loss or any other displeasingdeficiencies. The shield system 130 may include a first bracket 134 anda second bracket 136 that each may be adhered to a first tooth 138 and asecond tooth 140, respectively. The first and second brackets 134, 136may be similar to the bracket 104 described in FIGS. 8 and 9. The shieldsystem 130 also includes a shield member 142 that may include theaesthetic appearance of three teeth, namely, a first shield portion 144,a second shield portion 146, and a third shield portion 148, the firstand second shield portions 144, 146 being joined by a first intermediateportion 150 and the second and third shield portions 146, 148 joined bya second intermediate portion 152. The shield member 142 may include aface portion 154 and a rear portion (not shown). The rear portion mayinclude an opening and tab arrangement (not shown), similar to thatdescribed with respect to FIGS. 8 and 9, at the rear portion of thefirst shield portion 144 and the third shield portion 148. As such, theopening and tab arrangement in the rear portion (not shown) of the firstand third shield portions 144, 148 may respectively couple to the firstbracket 134 and the second bracket 136 in a similar manner as depictedin the embodiment of FIGS. 8 and 9. With this arrangement, the shieldmember 142 is retained by the first and third shield portions 144, 148and the second shield portion 146 aesthetically shields the gap 132between the first and second tooth 138, 140. The materials employed inthis embodiment may be similar to those described in the previousembodiment.

FIGS. 11-14 describe another embodiment for aesthetically shielding agap 184 or a lost tooth in one's teeth. FIGS. 11-12 depict oneembodiment of a shield member 160. The shield member 160 may include afront side 162 and a rear side 164 with an edge extending between thefront side 162 and rear side 164 that defines a periphery 166 of theshield member. The rear side 164 may include an extension portion 168with, for example, two ends 170 sized and configured to couple torespective first and second coupling members 178, 180 (See FIGS. 13 and14). As depicted in FIG. 11, the extension portion 168 may extend beyonda width or the periphery 166 of the front side 162. Such extensionportion 168 may be snipped or cut down to a desired length to match thewidth for a given gap between teeth. For example, FIG. 12 depicts theextension portion 168 with a longitudinal length (with the ends beingsnipped) so as to match the approximate width or periphery of the shieldmember 160. Further, the periphery 166 of the shield member 160 may becut or filed back to an appropriate size to match the gap 184 (FIG. 14)between one's teeth. Further, the rear side 164 of the shield member 160may include a backing 172 for additional reinforcement to the shieldmember 160.

As depicted in FIGS. 13 and 14, the shield member 160 is coupled betweena first tooth 174 and a second tooth 176 by coupling the extensionportion 168 to a first coupling member 178 and a second coupling member180. The first and second coupling members 178, 180 may be respectivelyadhered to an inside surface of the two teeth adjacent to the gap 184.The first and second coupling members 178, 180 each include a couplingconfiguration that corresponds with a respective end 170 of theextension portion 168. For example, as depicted in FIG. 13, the couplingconfiguration is a recess 182 formed in the first coupling member 178that is sized and configured to receive one end 170 of the extensionportion 168. The extension portion 168 may be formed of a resilientpolymeric material that can properly retain the shield member 160, butcan also be readily removed when desired. The front side 162 or frontportion of the shield member 160 may be formed of a thin polymericmaterial. The front side 162 of the shield member 160 may include one ofa variety of shades of white that can be matched to one's teeth. Withthis arrangement, the shield member 160 and first and second couplingmembers 178, 180 facilitate one to aesthetically shield the gap 184 inone's teeth.

The first and second coupling members 178, 180 may be formed of apolymeric material, ceramic, or metal, or combinations thereof or anyother suitable material as known in the art. The shield member 160 maybe formed of one or more materials. For example, the front side 162and/or the rear side 164 of the shield member 160 may be formed of apolymeric material, similar to those previously set forth, such aspolyvinyl, composites, ceramics, laminates or combinations thereof asknown by one skilled in the art. Further, the extension portion 168 andbacking 172 may be formed of a polymeric material as previously setforth and, preferably, a more compliant polymeric material, such assilicon rubber or the like.

Now with reference to FIGS. 15 through 17, another embodiment of ashield member 202 for purposes of aesthetically shielding one's tooth205 is provided. Such a shield member 202 may be employed for purposesof shielding the discoloration of one's tooth 205, in which case theshield member may be white or a white-like color to match the otherteeth in one's mouth. In another embodiment, the shield member 202 mayinclude a black color or any other color to be employed for, forexample, costume purposes.

The shield member includes a body portion 203 having a face surface 204and a rear surface 206 each defined by a periphery 208. The shieldmember 202 may include multiple suction cups 210 extending from the rearsurface 206. In another embodiment, the shield member 202 may includeone suction cup extending from the rear surface 206. Preferably, theshield member 202 may include between two and six suction cups 210, butmay exceed six suction cups as the suction cups 210 may be much smallerin comparison to that depicted so as to facilitate additional suctioncups. The suction cups 210 may each include a base 212 and a cup portion213, the cup portion extending from the base with a circularconfiguration. The base may be centrally located relative to thecircular configuration. The base 212 may be in the form of an extension,as depicted, or it may include a low-profile. For example, the base 212having a low-profile may simply be the interconnection between the cupportion 213 and the rear surface 206 of the shield member 202 such thatthe rear surface 206 defines one or more concave portions or suctioncups therein. Further, each cup portion 213 may include a suctioningsurface 214 extending from the base having a concave shape to facilitateeffective suctioning of each suction cup 210.

To apply the shield member 202 to a tooth 205, the user may first cleanand then dry an outer surface or face surface of the tooth 205. The usermay then remove the shield member 202 from its packaging and applymoisture to the suctioning surface 214 of each suction cup 210. Suchmoistening may be employed with the user's tongue or with a damp cloth.Once the suction cups 210 are moistened, the user may position and alignthe shield member 202 over a tooth 205 and then apply a force, asindicated by arrow 216, to the face surface 204 of the shield member 202such that the suctioning surface 214 of one or more suction cups 210 ispressed against the face surface 204 of the tooth 205. In this manner,the suction cups 210 of the shield member 202 become suctioned to thetooth 205 to, thereby, hold the shield member 202 to the tooth andconceal the face surface of the tooth 205.

Such shield member 202, along with the suction cups 210, may bemonolithically formed in a unitary and integral manner so as to be asingle piece member. In another embodiment, the shield member 202 may beformed separately and with a separate material than the suction cups 210such that the suction cups are added to the shield member employingvarious fastening techniques, such as, adhesive, wire fasteners, etc.Further, the shield member 202 may be formed of one or more polymericmaterials, ceramics, etc., similar to that described herein foralternate embodiments for a shield member. The suction cups 210 may alsobe formed with similar polymeric materials or any suitable polymericmaterial as known to one of ordinary skill in the art that willfacilitate effective suctioning of the shield member 202 to one's tooth.

In another embodiment, the suction cups 210 and shield member 202 setforth above may be employed as a shield system similar to the shieldsystem 130 depicted in FIG. 10. For example, at the rear portion or sideof a shield system, suction cups may be employed to a first and thirdshield portion to suction to teeth on both sides of a gap or anunsightly tooth such that a second shield portion extends between thefirst and third shield portions to hide the gap or unsightly tooth. Inthis manner, the suction cups may replace the need of adhering temporarystand-alone brackets to the teeth, as set forth and described relativeto FIG. 10.
